No issues with light burn w/ the MF2000 at 11 inches above canopy? I have the same light setup, with SE3000 for flower as well but keep mine up higher per the manual. But if you're seeing good results with them lowered I might have to give it a shot as well.
@bgreen1,I haven't tried to put the MF2000 that low. Might have to give it a try. But yeah your right, SE3000 if put to close it will burn your babies. Happy growing π€πͺπ
